Decided to post my versions of the FF gates, my amp gates, and an interesting bug that I came across. It seems that if you coat a block of particle-allowing (yellow) wall with metal and attach an input at the right spot, it will amplify the signal.
A 3 x 3 block of metal covering a piece of the wall yields a 3:1 amplification, while a 4 x 4 block yields an 8:1.
Just thought I'd share.
EDIT: solved the finicky 4 x 4 block problem; just needed an extra pixel of conductor hanging off the edge. Also, testing with other conductors yields the same results (NTCT requires PSCN to transfer current to it which necessitates a PTCT-NSCN break in the input wire to prevent backflow).
